put the camera under a thick blanket or similar and take a 10 or 20 second image. Its the only way to check out the light leak issue. Dont use the aluminium cap, leave it off.
Also make sure in the camera setup, you enable "Anti amp" light to ON.


Further, when ever you power up the camera, the buffers will contain junk, so the first shot is always junk. Do what Marc said, either a bias frame or very quick exposure, like .5 sec etc.. to clear the buffers.


To add further again, sorry, the light leaks are not consistant, meaning it may not be the camera, and something externally, as the light sources are moving indicating its an external source hampering your images. Maybe look into the scope during the exposure of your images, and see if theres a bright light comming down the scopes focuser, etc.
